Answer:
If both pens are the same color, it means that they are either black and black or red and red.If without replacement,pr. of first black and second black is
8/11 and 7/10.Also, the pr of the first red and sencond red pen= 3/11 and 2/10.
Therefore pr. of bb or rr
(8/11×7/10)+(3/11×2/10)
56/110+6/110 =31/50
For this case we must find the solution of the following equation:

Applying distributive property on the right side of the equation we have:

Subtracting 7x from both sides of the equation:

Subtracting 20 from both sides of the equation:

Different signs are subtracted and the major sign is placed.

Dividing between -2 on both sides of the equation:

Thus, the solution of the equation is
